I think Ted nailed it. It is most likely a shorted starting capacitor. If you have a multimeter you could check it for a short by setting it to high ohms and touch the leads to the terminals. If it starts out at a low reading and climbs to a high one the capacitor is probably good. If it stays low it is shorted. But even without testing if it runs when you rotate it but blows a fuse if you don’t do that the only thing different is the starting capacitor being in or out of the circuit. You can actually order one.
Just find it on the motor. (it will be tubular shaped rounded or oval)
See what the value is that is printed on it.
Google “induction motor capacitors”
You should then get a bunch of sites to get a replacement and order one that matches what you have.
Should not cost more than a few dollars.
When you get it just disconnect the old one and put on the new one making sure you replace the wires to the same terminals that you took the old ones off of.
